英文摘要	Dual-arc pulsed MIG welding is a low heat input welding method. In this welding process, two urgent problems should be solved first. One is the matching of pulse current waveforms for main and bypass arcs, the other is stability of coupled welding arcs. An embedded control strategy based on high performance digital signal processor (DSP) is proposed for these problems. Then the embedded control system for dual-arc pulsed MIG welding is set up by design of software and hardware. Based on the established system, time sequence control of pulse current waveform and various control algorithms in welding process can be achieved with flexibility through programming. Then bead-on-plate welding is carried out to join aluminum alloy to galvanized steel with a low heat input and a good weld formation between aluminum alloy and steel is obtained. The results show that the embedded control system can meet the control requirements of dual-arc pulsed MIG welding, improve the stability of welding process and achieve fine welding quality. © 2017, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding.
